sPEcIrIcArIoNfpr-miag pm. of Letters Patent No; 269,36@ dated December" 19, 1882 Application mea August 3.1m. (rinda.) i

To all whom it may concern Be it known that I, .I0-HN \V. \V1LSO.\, a citizen of the United States, residing at Ashmore, in the county` of Coles and State of lili nois,have invented certain new and nset'ui lmprovements in Cultivators; and Ido declare the following to bc a full, clear, and exact description ofthe invention,.such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanyingdrawings, and to the letters and figures ot' reference marked thereon, which form a part of this specification.

This invention has relation to improvements in cultivators, corn harrows, and similar implements; and it consists in the construction andarrangement of the several parts, as will be hereinafter` fully described, and specifically pointed out in the claitns.

1n the drawings, Figure 1 is a plan view,

. Fig. L is a front, elevation, Fig.3 is a. side view,

and Figs. 4, 5,6, and 7 are detail views, of a. de\ ice constructed according to my invention, as will be described` a a' represent ordinary shovel or cultivator' beams. The beam a is made longer than the beam a' in order to secure the toothed bar at an angle to the direction of the beams. These beams are connected at their forward ends, and near'their rear end I cut two boltholes for the purpose ofreceiviugthe bolts which secure tLe. loop-connection and the beams together.

brepreseuts the loop-connection. Its upper euri, b', is bent forward to bear against the forward. side ofthe standard of the beam, as shown in Figs. 2 and 3, and it is provided with holes b2' b3wher'eby it is secured by bolts or pins to the. standard. The loop is substantially pivoted to the standard by a strong pin placed through the hole b2, and its upper end is held to the standard by a wooden pin-,b, placed through the hole b3 anda coincident one inthe standard. Thus when the harrowing-teeth come in Contact, with any immovable obstruction this wooden pin will `break and the loop carrying the toot-hed bar will swing back and escape over the obstruction, when the upper end of thc loop may again be secured byan other wooden pin, a number of which may he carried when had ground is bcingprepared. The lower end of the loop extends below the end of the beam and provides a slot iu which the bolt securing the linee may be WUUSO to set the latter higher or lower, n.8 may be desired.

lt will he understood that by bifniilnf! the lower end of the beam, and thus ptm'ldlllg vertical opeiiing,or forming it with ti slOtq gQod result would be accomplished; but! prefer ille use ofthe loop, asshown, as by it l gam better results, and also t-he parts can DP more readily and cheaply repaired in cas 0f breaka e.

.gcrepreseutsthekneesecuringthetothedbar and the connecting-loop. It. is bent t0 DFOVI'B the arms c' e. The arm c' is provided with two bolt holes, vthe upper one ot' which is threaded to receive the tbreadcd sei=screw d, whilethe loweronead mits the bolt c, till@ head 0f which bears against lhearm c',andrit lfbl'llded through the knee andthe opening,r in IOWFI end of loop-connection b, and is seclil'td by I llll e', screwed ou the end ofthe holte, and hearing against the rear of thecounection b, n SllOflll. Byloosuing the nut e' the linee hilly be tldjusted up or down in the connection I'. HS may be desired. The set-screw turnsin n illfiafld opening, c5, in the knee c and bent gl the beam, and by turning this screw ille klli may be set to adjust the teeth to nhygdGSlH-fd pitch, the bar being braced by the lmCl`0d having its forward end slotted, as will be de scribed. Through the arm c2 of the lince Iclll a slot, c, through which is passed th@ boli/,01, which secures the knee and tooth-bat' OgGtlter. The slot permits an adjustment ofbolt U, which is often desirable.

f represents the tooth-carrying but, I C 1S made in two scctions,ff, as shown ill Figs. 1 and 2, so that the sections, being secured by bolt c3, and thus practically pivoted un lll@ lOOt of the standard, may be sctatditierci angles and on opposite vsides ot' a row, ne @110ml lll d ottcd lines, Fig. 1, providing a sttnddl-IQW cultivator. 'lfhetceth beii-igatljustnlll,\8 'lll be described, can be setto work properly with the di'erent draftangles'ot' the bnr, und byrcmoving the vsect-ion from the longhi' 0F rear beam,a, and securing a cultivator-shmYl thereto, I can barrow next the corn and lilOyV between the rows at the same time. '.1 hc inner or 'meeting ends of these sections nl Iliad@ square, and they are connected togctlllpya plate, g, lapping thejoint, asshown iu Fig J.

This plate is's'ecured to one section by -the shank and nutof one-of the teeth, and tothe other 'section by one of the teeth and the boltg', and the meeting ends being` square and abutted closely together, they are firmly held', and form substantially a single bar.

YVhen so desired, the plate g may be made long enough to extend ,from one to the other ofthe sectionsf' when they are turned apart and brace tlieiu in their straddle-roiv positions. When the adjustable sections are not desired the bar may be made in a single piece, as shown in Fig. 4.

f2 are elongated slots eut in the. sectiouf, through which are passed the bolts ci. seciiring the knee and bar together. 'hen the two sectiousf'arc used this slot is advantageous, in that it permits the adjacent ends ofthe sections to be adjusted to and away from each other, and also to enable the bars to be set at any angle desired on any ordinary ciiltiv'ator the beams of which are not made of a uniform distance apart, and these slots are used when a single bar is employed to facilitate its connection to cullivators of various widths.

f3 represent bolt-holes formed in the b arf, to admit the threaded rangs otthe teeth and bull-tooth, hereinafter described.

f represent the teeth; f5, the bull-tooth. They are provided at. their upper end with round threaded tangsf, adaptedA to be placed through the bolt-holesf3 and secured b v nuts f. These teeth are curved forward, as shown, and, being Connected by tang and nut, may be readily turned to adjust themselves to the different angles to which the sections of barfare set, or they may be entirely reversed, so as to curve back, in which position they are often used' to greatadvantage in a corri-field. teeth and bulI-tootli are made thickest at their upper end and gradually diminished toward their lower end. The teeth are made of about an equal width from top to bottom, while the bull-tooth is constructed with its shank about the saine width as the teeth, and with its end extended below the end of the teeth and made wider, as shown in Fig. L. This bull-tongue is arranged at tbe end of the bar fand runs close to the corn, and, being longer than the other teeth, gives the section a steady run, and by its peculiar shape throws the dii-t up better to the corn-row.

h represents a bar having its` rear end bolt- The ed to outer end of the section f. The forward -end of this bar is extended to the cultivatorbeam` and is provided with a slot, h', through which is passed the bolt h2, which secures it to the beam. This slot h' is open at its forward end, so that'itniay pull out; from the securing-pin when the toothed section is swun,r baclr, as hereto-fore described. B v loosening the bolt h2 the rod his permitted to be moved forward or back as the barf is tilted by the setserew rl, as has been described.

llhis invention can readily be adapted and Aattached to any corn-coltivator, either on wheels or runners, tli-e object being,r to provide a. means whereby to eiiiciently cultivate corn or vegetables that are planted in hills or drills when small. made in two sections and secured to the beam by knees and loop-connections, as shown, provide a convenient and etiicient adjustment and fastening, as described.

Having thus` described my invention` what I claim, and desire to secure by Letters Patent, is- 1. In a cultivatoraiid corn-barrow, the combination, substantially as described, of the cultivator-beam, the bar f, the brace-rod h. having;r one end secured to outer end of barf and its opposite end slotted and connected to the beam, the knee c, secured to the bar f' and to the foot of the standard, and the adjustiner set-screw d, as set forth.

2. The combination, with the diveiging beams a. a', secured together at their forward ends, ofthe sectional toothed carrying-liar f, having the sections ff', secured adjustably to the rear ends of the beams, as and for the purposes set forth.

3. In a cultivating-harrow, the combination,

substantially as described and sliowi.i,`of the diverging beams, connected together attheir forward ciids, the pivoted connection-loops, having their upper ends secured by a fragile pin, the knees, the adjusting set-screw, the agljustable toothed sections, the connection-plate g, and the brace h, as and for the purposes set torch.

1n testimony whereof I aftix my signaturein presence ot' two witnesses.
